arXiv:2606.25447v1 Announce Type: new Abstract: Tool-integrated LLM agents are often wrapped within a harness: the scaffolding that determines which tools are exposed, how they are described, and what auxiliary information accompanies each per-step observation. While agents are routinely post-trained, this scaffolding is typically treated as a fixed engineering detail, with design effort limited to the training-free regime. Moreover, existing post-training algorithms assume a static environment, even though tool environments and tasks often shift upon deployment. To address this gap, we extend
The rapid deployment and increasing sophistication of LLM agents in real-world applications necessitate more robust and adaptable training paradigms that account for dynamic operational environments.
This research addresses a critical limitation in current LLM agent development by enabling them to adapt to changing tool environments and tasks, making them more reliable and broadly applicable in enterprise settings.
The focus shifts from fixed agent scaffolding to dynamically adaptable harness designs and post-training methods, allowing agents to maintain performance as their operational context evolves.

LLM agents become more resilient and effective in diverse, real-world deployment scenarios.
This improved adaptability accelerates the adoption of AI agents across various industries, replacing more white-collar tasks.
The development of highly adaptable AI agents could lead to more complex, autonomous systems that significantly alter workflow automation and require new paradigms for oversight.
